Understanding the fundamental nature of dark matter is one of the major
challenges facing the physics community today. Direct and indirect
detection efforts search for dark matter interactions with the Standard
Model of particle physics, but no concrete evidence has been observed.
In this talk, I will discuss how cosmological observables can be used as
complementary probes of dark matter physics. In particular, I will
describe the effects of dark matter scattering with protons and
electrons in the early Universe and show constraints using CMB
anisotropies and the Milky Way satellite abundance.
Zoom link will be sent to the astro@physics.illinois.edu mailing list. There will be an informal meet-and-greet with the speaker at 11:30am Central.
